Fixed the crash: http://hg.dovecot.org/dovecot-2.0/rev/e392f5f65cd8

But the main problem you have is that you don't have a passdb and your
userdb is static. So Dovecot can't verify if the user exists or not.
Either use a passdb or userdb that can verify user existence, or add
allow_all_users=yes to userdb static args.
